Gigapans

Barnhardt Canyon lies off of Arizona Route 87 just before reaching Payson. A four mile dirt road leads to the Barnhardt trailhead, and this gigapan was shot about 1.5 miles into the trail. The area is defined by folds - from the famous Diving Fold (not shown) to the wonderful Chevron Folds in the left hand side of this...

The Swift Dam area northwest of Depuyer, Montana, showcases Sever-style mountain building of the Cordilleran fold-and-thrust belt. Here, Mississippian carbonates have been arched eastward along asymmetric anticlines, and thrust over Cretaceous black shales originally deposited in the Western Interior Seaway. Notice how...

A Sevier-style thrust fault exposed west of Augusta, Montana, the French Thrust has emplaced Mississippian carbonates on top of Cretaceous shales. On the left (east), there is also some till, outwash, and colluvium. View is approximately to the south.

You're looking down the nose of this overturned anticline of Mississippian carbonate. Search for fossil coral heads and extensional fractures on the outside edge of this giant Sevier-aged thrust.

Taken from a higher vantage point, this view encompases the Red Rock Canyon in the foreground (Jurassic Aztec Sandstone) and the Keystone Thrust and overthrust Paleozoic section (darker colors) in the distance.
